--- Comment #26 from Robin Dapp <rdapp at gcc dot gnu.org> --- So insn-opinit.cc still takes 2-3 minutes to compile here, even though the file is not gigantic. With the same GCC 13.1 x86 host compiler I see: phase opt and generate : 170.28 ( 99%) 0.75 ( 48%) 171.43 ( 99%) 561M ( 60%) callgraph functions expansion : 35.04 ( 20%) 0.50 ( 32%) 35.65 ( 21%) 356M ( 38%) callgraph ipa passes : 135.02 ( 79%) 0.24 ( 15%) 135.55 ( 78%) 96M ( 10%) tree Early VRP : 127.83 ( 75%) 0.00 ( 0%) 128.11 ( 74%) 3141k ( 0%) Would need to re-check if this still happens with a GCC 14 host compiler. If so, that might be worth investigating as it seems pretty localized.
